Section 6.8                                    Entire Agreement. This Agreement (including the documents and the instruments referred to herein), together with the Key Holders Exchange Agreement, constitutes the entire

11

agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements and undertakings.

Section 6.9                                    Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other party; provided that Parent may assign this Agreement to any of its Affiliates. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns. This Agreement (including the documents and instruments referred to herein) is not intended to and does not confer upon any Person (other than the parties hereto and, solely with respect to Section 6.15 hereof, the No Recourse Parties (as defined below)) any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein.

Section 6.10                             Severability. The provisions of this Agreement shall be deemed severable. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction or the application of that provision, in any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that a suitable and equitable provision shall be substituted for that provision in order to carry out, so far as may be valid and enforceable, the intent and purpose of the invalid or unenforceable provision.

Section 6.11                             Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached and that the parties may not have an adequate remedy at Law in the event that any of the obligations of this Agreement were not performed in accordance with its specific terms or otherwise breached. Accordingly, the parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at Law or in equity, including monetary damages. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at Law would be adequate, (b) an award of performance is not an appropriate remedy for any reason at Law or equity, and (c) any requirement under any Law to post security or a bond or similar undertaking as a prerequisite to obtaining equitable relief.

Section 6.12                             Fees and Expenses. Except as otherwise provided herein, whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses.

Section 6.13                             Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Stockholder Owned Shares or Stockholder Owned Units. All rights, ownership and economic benefits of and relating to the Stockholder Owned Shares and the Stockholder Owned Units shall remain vested in and belong to the Stockholders, and Parent shall have no authority to direct the Stockholders in the voting or disposition of any of the Stockholder Owned Shares or the Stockholder Owned Units, except as otherwise provided in this Agreement.

Section 6.14                             Capacity. Parent acknowledges that nothing herein shall limit or affect any Affiliate of any Stockholder who serves as an officer, manager or director of the Company or any of its subsidiaries solely to the extent acting in its capacity as an officer, manager or director of the Company

12

or any such subsidiaries, and no actions or omissions of any such Affiliate acting in such capacity shall be deemed a breach of this Agreement by any Stockholder. For purposes of this Section 6.14, the term Affiliate shall be deemed to include, with respect to either Stockholder, the directors, managers, officers, members, partners, stockholders and employees of such Stockholder or any Affiliate or Related Fund of such Stockholder.

Section 6.15                             Non-Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, and notwithstanding the fact that the Stockholders may be partnerships, the parties hereto covenant, agree and acknowledge that no recourse under this Agreement shall be had against any former, current or future directors, officers, agents, Affiliates, limited partners, general partners, members, managers, employees, stockholders or equity holders of any Stockholder, or any former, current or future directors, officers, agents, Affiliates, employees, general or limited partners, members, managers, employees, stockholders or equity holders of any of the foregoing, as such (any such Person, a “No Recourse Party”), whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable Law, it being expressly agreed and acknowledged that no liability whatsoever shall attach to, be imposed on or otherwise be incurred by any No Recourse Party for any obligation of any Stockholder under this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.

Section 6.16                             Obligations Several. The obligations of the Stockholders under this Agreement shall be several and not joint and several.
